This book provides significant insights into the historical and theological development of classical Pentecostalism in the process of contextualisation in the Malaysian socio-cultural and multi-faith context. It is a systematic and comprehensive investigation into how the Assemblies of God Malaysia progresses from a classical Pentecostal movement towards the new identity of a "Contemporary Pentecostal Church Movement," and the way forward for missions and Pentecostal spirituality in this twenty-first century.
